Introduction and hypothesis: We evaluated patients’ perception and satisfaction with nonsurgical pulsed magnetic stimulation (PMS) for treatment of female stress urinary incontinence (SUI) in a randomized, double-blind, sham-controlled trial. Methods: Women with SUI (n = 120) were randomized to either active or sham PMS for 8 weeks (twice/week). Patients answered seven questions on their perception and acceptability, each measured on a 5-point Likert scale. Treatment satisfaction was assessed using two parameters: (i) the single-item question “Overall, please rate how satisfied you are with the treatment” and (ii) Patient Global Impression of Improvement (PGI-I). All adverse events were documented. Results: A total of 115 patients completed treatments (active: n = 57, sham: n = 58). There were no significant differences between groups in all parameters regarding perception and acceptability (p > 0.05). In terms of treatment satisfaction, a significantly higher proportion of patients in the active group (n = 47/57, 82.4%) were either mostly or completely satisfied compared with those in the sham group (n = 27/58, 46.6%) ((p = 0.001). Similarly, a statistically significantly higher percentage of patients in the active group (n = 39/57, 68.4%) felt much or very much better compared with patients in the sham group (n = 11/58, 19.0%) as measured using the PGI-I (p < 0.001). Three (5.3%) patients in the active group and five (8.6%) in the sham group experienced adverse events (p = 0.72). Regardless of treatment arms, 109 (94.8%) patients would not consider surgical options even if they required further treatment for their condition. Conclusion: PMS was well accepted, well tolerated, and resulted in a high treatment satisfaction among women with SUI. Refereed/Peer-reviewed

Association Introduction and hypothesis: We evaluated the effects of pulsed magnetic stimulation (PMS) on overall and different aspects of quality of life (QoL) in female patients with stress urinary incontinence (SUI). Methods: This study involved 120 female SUI subjects aged ≥21 years old randomized to either active or sham PMS. Treatment involved two PMS sessions per week for 2 months (16 sessions). After 2 months, subjects could opt for 16 additional sessions regardless of initial randomization. The primary response criterion was a 7-point reduction in the total score of the International Consultation on Incontinence Questionnaire-Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTSqol) questionnaire. Follow-ups were conducted at months 1, 2, 5, 8, and 14. Results: At 2 months, 35 out of 60 (58%) subjects in the active arm and 21 out of 60 (21%) in the sham arm were treatment responders (≥7-point reduction) (p = 0.006). There was a significant difference in changes in the mean ± SE ICIQ-LUTSqol total score between the active and sham arms (M diff = −8.74 ± 1.25 vs −4.10 ± 1.08, p = 0.006). At 1-year post-treatment, regardless of number of PMS sessions (16 or 32 sessions), subjects who received active PMS (63 out of 94, 67%) were more likely to be treatment responders compared with subjects who did not receive any active PMS (3 out of 12, 25%; p < 0.001). The impact of PMS treatment was the greatest on the “physical activities” domain. Conclusions: PMS resulted in significant short- and long-term improvements in overall and various physical, social, and psychological aspects of QoL. Refereed/Peer-reviewed

Background There is currently a lack of randomized, sham-controlled trials that are adequately powered, using validated outcomes, to allow for firm recommendations on the use of magnetic stimulation for stress urinary incontinence. We report a protocol of a multicenter, randomized, double-blind, sham-controlled parallel-group trial to evaluate the efficacy of magnetic stimulation for stress urinary incontinence. Methods/Design One hundred twenty subjects with stress urinary incontinence will be randomized in a 1:1 allocation to either active or sham magnetic stimulation using computer-generated, permuted blocks of variable sizes. Subjects will receive 2 sessions of magnetic stimulation per week for 8 weeks (16 sessions total). The primary outcome is the improvement in severity of involuntary urine loss based on the International Consultation on Incontinence Questionnaire for Urinary Incontinence Short Form at the end of treatment sessions compared with baseline. Secondary outcomes include cure, stress urinary incontinence–related symptoms (incontinence episode frequency, urine loss in 1-hour pad test, pelvic floor muscle strength) and health-related quality of life (Patient Global Impression of Improvement, International Consultation on Incontinence Questionnaire–Lower Urinary Tract Symptoms Quality of Life and EQ-5D). The safety of magnetic stimulation will also be assessed. Besides evaluation of clinical treatment effectiveness, cost-effectiveness analysis using patient-reported outcomes will be performed. Discussion This trial is designed to provide pending outcome information on this non-invasive treatment option. We intend to acknowledge the existing flaws in previous clinical trials and determine conclusively whether magnetic stimulation is effective for stress urinary incontinence.
